one integral piece made from a sheet died out and bent the proper shape. The flange 8 may extend continuously they entire length ol the closure piece. The flanges 9 are interrupted'by the knuckle portions and consist of a series of short-flanges each of length equal to the spaces between the knuckles. The channel pieces should be mitered at their ends to form a smooth joint, as shown in dotted lines'in Fig. 1. It will thus be seen that' the same member serves both as a hinge and as a closure for the edge space between the walls and it not only gives a finishedV appearance to the edge but it .stiffens and strengthens the panel.

' By making the hinge as a separate piece Jrom the inner or outer wall plate of the li (l panel, the hinge can be made of heavier stock than is required for the sheets of metal which form the innerand outer Wall plates, thus gaining stillness at the hin e lwhile not materially increasing the weig 1t of the panel.
